IJC releases new geospatial map of Canada-United States transboundary basins

The International Joint Commission (IJC) is pleased to announce the availability of a new map showing transboundary drainage basins shared by Canada and the United States and describing the IJC activities in these basins. The new map is based on geospatial data that has been harmonized between the two countries. The Activities Map is one of a series of products that recognize the 100th Anniversary of the Boundary Waters Treaty of 1909 that created the IJC, including a Centennial Edition of the IJC Activities Report and a Centennial Website.

Over the years, each country has developed its own suite of hydrographic datasets, using slightly different standards and interpretive rationales. Until recently, such data sets at a scale usable for planners and managers at the basin level have stopped at the boundary, preventing the seamless exchange of hydrographic data and associated study results.

Hard copies of the map are available from the IJC’s Washington and Ottawa offices, and online: at www.ijc.org.
